Helmed horrors were magically animated suits of armor created to act as guardians. Unlike lesser animated constructs, helmed horrors possessed a limited but effective form of intelligence, allowing them to follow complex commands and adapt to changing circumstances in battle. They were often used by Spellcasters or institutions to guard vaults, temples, or arcane secrets. Once given a directive, a helmed horror carried it out without hesitation, ignoring distractions and showing no regard for self-preservation.
These constructs floated slightly above the ground and moved with unnatural silence, their hollow armor glowing faintly with magical energy. Helmed horrors were immune to many spells and effects, including most illusions, charms, and mind-altering magic, making them especially dangerous to those who relied on magic. They could be customized to resist specific types of damage or even wield particular weapons.
